Your previous 'Debian GNU/Linux (8.6) (on /dev/mmcblk0p1)' stanza had
linux /boot/vmlinuz-3.16.0-4-686-pae root=/dev/mmcblk0p1
This one has
linux /boot/vmlinuz-3.16.0-4-686-pae root=UUID=e57b2c64-74ec-4184-af71-d807e07f07dd ro quiet
The UUID has changed (I think you said you had done this) but the kernel
now looks for init using the UUID rather than on /dev/mmcblk0p1. How did
you manage to get something significantly different?
During the first install of Debian to the SD card I allowed the installer to
create a single partition filling the whole card. The primary purpose of
that install was a brute force determination of whether or not my individual
machine could read/write an SD card. The machine was a replacement for a
different used machine purchased from the vendor. My accepting the SD card
was dependent on that test.
I had reinstalled Debian to a more reasonably sized partition. That would
explain a changed UUID. During the reinstall I experimented with installing
grub to the MBR of the SD card. No grub was installed the first time.
The UUID change is understandable. But hey - you've altered the ground
rules! Now, it seems, you are exploring booting from the card itself
rather than from GRUB on a hard disk.
